More good stuff in the Objective-C department. Patrick Beard over on the
objc-language Apple mailing list brough up the new syntax for boxed
expressions they are working on. You’ve probably noticed the
ability to specify numeric literals in the upcoming Xcode like

But you weren’t able to pull that off at run time. With this change coming,
you’ll be able to use that syntax to automatically box numbers and strings with
this new syntax. Apple cleared a lot of cruft out of the way by supporting
clang development to replace gcc. These new syntax changes are coming faster
and faster, now.
